       The  Internet  being  what  it  is,  absolutely  anything might show up in the collage including -- quite
       possibly -- pornography, or even nudity.

       This screen saver creates collages out of random images from the World Wide Web.  It finds the images  by
       feeding  random words into various search engines, then pulling images (or sections of images) out of the
       pages returned.  One satisfied customer described it as "a nonstop pop culture brainbath".

DISPLAY to get the default host and display number.

       XENVIRONMENT
               to  get  the  name  of  a  resource  file  that  overrides  the  global  resources  stored in the
               RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

       http_proxy or HTTP_PROXY
               to get the default HTTP proxy host and port.

/usr/dict/words,/usr/share/lib/dict/words, or /usr/share/dict/words to find the  random  words  to  feed
       into to various search fields, including Google, Bing, Flickr, Imgur and Tumblr.

       webcollage - a collage of random images from the World Wide Web

webcollage accepts the following options:

       --root or --window-idnumber
               Draw  on  the  specified  window.   Images  are   placed   on   the   root   window   using   the
               xscreensaver-getimage(6x) program.

       --verbose or --v
               Print  diagnostics to stderr.  Multiple -v switches increase the amount of output.  -v will print
               out the URLs of the images, and where they were placed; -vv will print out any warnings, and  all
               URLs being loaded; -vvv will print information on what URLs were rejected; and so on.

       --timeoutseconds
               How  long  to  wait  for  a URL to complete before giving up on it and moving on to the next one.
               Default 30 seconds.

       --delayseconds
               How long to sleep between images.  Default 2  seconds.   (Remember  that  this  program  probably
               spends a lot of time waiting for the network.)

       --backgroundcolor-or-file
               What  to  use  for  the  background  onto  which  images are pasted.  This may be a color name, a
               hexadecimal RGB specification in the form '#rrggbb', or the name of an image file.

       --sizeWxH
               Normally, the output image will be made to be the size of the screen (or  target  window).   This
               lets you specify the desired size.

       --opacityratio
               How transparently to paste the images together, with 0.0 meaning "completely transparent" and 1.0
               meaning  "opaque."   Default  0.85.   A  value of around 0.3 will produce an interestingly blurry
               image after a while.

       --no-output
               If this option is specified, then no composite output image will  be  generated.   This  is  only
               useful when used in conjunction with --verbose.

       --urls-only
               If this option is specified, then no composite output image will be generated: instead, a list of
               image URLs will be printed on stdout.

       --imagemapfilename-base
               If  this option is specified, then instead of writing an image to the root window, two files will
               be created: "base.html" and "base.jpg".  The JPEG will be the collage; the HTML file will include
               that image, and a series of clickable rectangles linking the sub-images to  the  pages  on  which
               they were found, as seen on the web version of WebCollage at https://www.jwz.org/webcollage/--filtercommand
               Filter  all  source  images through this command.  The command must take a PPM file on stdin, and
               write a new PPM file to stdout.  One good choice for a filter would be:

                    webcollage -root -filter 'vidwhacker -stdin -stdout'

       --filter2command
               Filter the composite image through this command.  The -filter option applies to  the  sub-images;
               the -filter2 applies to the final, full-screen image.

       --http-proxyhost:port
               If  you  must  go  through a proxy to connect to the web, you can specify it with this option, or
               with the $http_proxy or $HTTP_PROXY environment variables.

       --dictionaryfile
               Webcollage normally looks at the system's default spell-check dictionary  to  generate  words  to
               feed into the search engines.  You can specify an alternate dictionary with this option.

               Note  that by default, webcollage searches for images using several different methods, not all of
               which involve dictionary words, so using a "topical" dictionary file will not, in itself,  be  as
               effective as you might be hoping.

       --directorydir
               Instead of searching the web for images, use the contents of the given directory.

       --fps   Display the current frame rate and CPU load (MacOS only).
